In the fields of chemical industry, pharmaceuticals, bioenergy, etc., n-butanol is an important solvent and chemical raw material, and its efficient and high-purity separation and recovery are crucial. However, the azeotrope formed by n-butanol and water complicates traditional distillation separation…

With the booming development of industries such as electroplating, metallurgy, and battery manufacturing, the treatment of large amounts of zinc-rich waste acid has become an environmental and resource problem that needs to be solved urgently. Traditional chemical precipitation methods are…

In cutting-edge fields such as and high-purity metal preparation, tributyl phosphate (TBP) plays an irreplaceable role as a highly efficient and selective extraction agent. With its unique molecular structure, TBP can precisely “capture” target metal ions in solution, enabling the…

Sulfolane, a highly effective solvent, is widely used in the chemical and pharmaceutical industries. However, its wastewater discharge has become a major environmental challenge for these companies. Traditional recovery methods are inefficient, energy-intensive, and result in significant solvent loss, leading…

In the acrylic acid extraction process, traditional extraction and separation processes often face challenges such as low efficiency, high solvent consumption, and easy emulsification, which directly impact production profitability. Zhengzhou Tiei Extraction Technology’s CWL-M series centrifugal extractor, with their unique…

In the precision manufacturing process of active pharmaceutical ingredients (API), efficient extraction and separation of reaction mixtures are the core links that determine product purity, yield and cost. With the increasingly stringent global drug regulation and the deepening of the…
